At many schools and businesses, Friday is a day to dress down. Casual Friday, it is sometimes called. Casual Friday is a nice way to relax after a week of hard work. At Pinnacle Classical Academy, Friday is not a dress-down day. In fact, at PCA, Friday is known as Formal Friday. The students dress up from their normal weekly uniforms to formal plaid jumpers and skirts, pressed white dress shirts, and pants and ties for the boys. Why do we do that?
